Abstract

The viscosity, lifetime, and structure of melts of supramolecular H-bonded complexes of acid diethyl and dimethyl esters of 3,3',4,4'-(diphenyl oxide)tetracarboxylic or 3,3',4,4'-diphenyltetracarboxylic acids with aromatic diamines (diaminodiphenylmethane or m-phenylenediamine) are studied.
